You can put this solution on YOUR website!
Break up the x-axis into a number of steps.
How about 4 steps each 1 unit long.
Start at x=-1.
Calculate y.
x=-1,y=2%5E%28-1%29=1%2F2, (-1,1/2)
x=0,y=2%5E%280%29=1, (0,1)
x=1,y=2%5E%281%29=2, (1,2)
x=2,y=2%5E%282%29=4, (2,4)
x=3,y=2%5E%283%29=8, (3,8)
Plot those points.

You can then connect the points with straight lines.

Here is the graph of the actual function layed over the linear representation to show good a job the linear representation does.
